Install a suitable lifting device through the center of vibration damper (4). The weight of a narrow vibration damper is approximately 288 kg (639 lb). The weight of a wide vibration damper is approximately 402 kg (882 lb).
Align the Timing Mark for the TC position on vibration damper (4) with the Timing Mark on the crankshaft. Be sure that the bolt holes are aligned. Place vibration damper (4) on Tooling (A). Be sure that the heads of the small bolts at the center of the vibration damper fit into the spacer. Install vibration damper (4).
Illustration 3 g01294011
Install adapter (3) on Tooling (A). Be sure that the bolt holes are aligned. Be sure that the heads of the small bolts at the center of vibration damper (4) fit into adapter (3).
Apply Tooling (C) to the threads of the bolts that go through adapter (3) and vibration damper (4) and bolt to the crankshaft.
Install the bolts that go through adapter (3) and vibration damper (4) and bolt to the crankshaft. Tighten the bolts in a diagonal pattern to a torque of 1350 150 N m (1000 110 lb ft).
Remove Tooling (A) and install Tooling (B) in adapter (3).Note: Ensure that the outer vibration damper is installed in the correct orientation. The Timing Mark for the TC position should be turned 36 degrees in a clockwise direction from the Timing Mark for the TC position on vibration damper (4). The direction is determined when the dampers are viewed from the front of the engine.

This is an Illustration of Dual Vibration Dampers.
Install a suitable lifting device through the center of vibration damper (2). The weight of a narrow vibration damper is approximately 288 kg (639 lb). The weight of a wide vibration damper is approximately 402 kg (886 lb).
Install vibration damper (2). Be sure that the bolt holes in the vibration damper are aligned with the threaded holes in the adapter. Be sure that the heads of the small bolts at the center of vibration damper (2) fit into the adapter.
Apply Tooling (C) to the threads of bolts (1).
Install bolts (1) that hold vibration damper (2) to the adapter. Remove Tooling (B). Install remaining bolts (1). Tighten the bolts in a diagonal pattern to a torque of 1350 150 N m (1000 110 lb ft).End By:
Install the damper guard group.
